Prototyping with Revolution Pi: What You'll Need

Power Supply for the Workstation

For safety reasons, you must not use power supplies for DIN rails at your workplace. We therefore recommend the following equipment:

Plug-in power supply

• Input voltage: 100–240 V AC
• Output voltage: 24 V DC
• e.g. Mean Well GST36E24-P1J or comparable

Note on power output:

Choose a power supply unit whose power output is designed for the power requirements of your entire system (base module, expansion modules, and connected sensors and actuators).

DC Cable Socket

• A cable with a barrel connector on one side and two open cable strands on the other.
• This is used to connect your plug-in power supply to your Revolution Pi – via the screw terminals of the X4 connector (RevPi Connect and RevPi Core).

Note: You should first fit ferrules to the open cable ends (more on this below).

Tools & Materials for Cabling

Cable

• PVC stranded wire, 0.5 mm² cable cross-section

Ferrules

• Power supply for the base module:
  • Standard ferrules: 0.5 mm² partially insulated, 8 mm long
• Power supply for the expansion modules:
  • Twin ferrules: 0.5 mm² partially insulated, 8 mm long
• Connection of sensors and actuators (for I/O modules with 14-pin connector):
  • Long ferrules: 0.5 mm² partially insulated, 12 mm long

Tools

• Wire stripper
• Crimping pliers for ferrules
• Screwdriver

DIN Rail for Mounting (Optional)

DIN rail

If you use expansion modules, it makes your work easier to attach your Revolution Pi system to a DIN rail.

Note on ventilation:

Please note that the devices are only 100% efficient if the ventilation slots are unobstructed and the device is mounted vertically. (learn more)

Distribution terminal block

This allows you to distribute the 24 V voltage from the power supply to multiple outputs.

This is helpful if you want to supply the base module and expansion modules from one single source.

• e.g., Weidmüller 2506380000 or comparable

Power Supply for I/O Modules and Gateways

You can power your expansion modules from the same power source using twin ferrules via the X4 connector on your RevPi base module.

If you have more than one expansion module, run the power supply with twin ferrules from one module to the next.

Do you have space on your DIN rail? Then you can also use distribution terminal blocks. These allow you to conveniently supply all modules with power.

Data Connection via Plug and Play

To enable data exchange between the base module and expansion modules, use the PiBridge plug connector.

No tools are required. It is a simple plug-and-play system: plug it in, set up the I/Os in the configuration tool PiCtory, and you're done.

Each expansion module comes with a PiBridge.
